# @ECLASS: autotools-multilib.eclass
# @MAINTAINER:

# @BLURB: autotools-utils wrapper for multilib builds
# @DESCRIPTION:
# The autotools-multilib.eclass is an autotools-utils.eclass(5) wrapper
# introducing support for building for more than one ABI (multilib).
#
# Inheriting this eclass sets the USE flags and exports autotools-utils
# phase function wrappers which build the package for each supported ABI
# when the relevant flag is enabled. Other than that, it works like
# regular autotools-utils.
#
# Note that the multilib support requires out-of-source builds to be
# enabled. Thus, it is impossible to use AUTOTOOLS_IN_SOURCE_BUILD with
# it.

# EAPI=4 is required for meaningful MULTILIB_USEDEP.
